Definitions

  • the present invention relates to a wheel suspension for vehicles, in particular commercial vehicles.
  • Wheel suspensions of the type mentioned above are known from U.S. Pat. No. 5,379,842.
  • the floor section of the vehicle has attached to it a mounting head which carries a bracket in a manner that allows the latter to be rotated about an upright axis.
  • the bracket is supported relative to the ground by wheels.
  • the bracket is designed to be intrinsically vertically adjustable to ensure uniform load distribution during use on uneven terrain and when a plurality of such wheel suspensions are used as supporting units, for heavy loads for example.
  • the mounting head carries a ring gear and the bracket, for its part, is connected, at the circumference of its top part which is supported relative to the mounting head and is not vertically adjustable, to an actuating motor which has an upright axis of rotation and engages in the ring gear by way of its drive pinion, which is provided at the upper end.
  • JP-A-60 135323 has furthermore disclosed a pivoted-wheel arrangement for a truck.
  • a guide ring which is fixed relative to the vehicle, on the floor, determines the pivoting axis of the vehicle and is coaxial with the axis, and to which is assigned, in a coaxially torsionally rigid manner, an internally toothed ring gear and a supporting ring.
  • the supporting ring is offset axially towards the wheel in relation to the ring gear, is rotatable, and carries the wheel with an axis of rotation perpendicular to the upright pivoting axis, an associated wheel hub motor and an upright actuating motor.
  • the invention is intended to develop a wheel suspension of the type stated at the outset in such a way that, without complicating its structure, a largely play-free driving connection can be achieved between the actuating motor and the ring gear as a prerequisite for a steering system that is, as far as possible, without play.
  • the supporting ring With a view to providing as compact a construction as possible, it has proven expedient for the supporting ring to be internally toothed and for the actuating motor to receive counter support against the outer circumference of the supporting ring.
  • the structural complexity can be kept relatively low while ensuring a small overall volume if the actuating motor is arranged vertically on the bracket, carries the drive pinion in the upper end region and is connected to the bracket by struts that are at an angle to one another and, with the bracket as the base, form a supporting triangle in plan view.
  • Such a solution makes it possible to keep the ring gear and the pinion in mesh virtually without play even if the actuating motor is connected to the bracket and the bracket, for its part, undergoes certain deviations from the position in which it is concentric with the supporting ring due to play and/or loads.
  • FIG. 1 shows a side view of one configuration of a wheel suspension according to the invention
  • FIG. 2 shows a front view of the wheel suspension shown in FIG. 1,
  • FIG. 3 shows a plan view of the wheel suspension shown in FIGS. 1 and 2, substantially without the mounting head,
  • FIG. 4 shows an illustration corresponding to FIG. 3 with the wheel turned by 45° relative to the straight-ahead position shown in FIG. 3,
  • FIG. 5 shows a partial view of the mounting head on an enlarged scales
  • FIG. 6 shows an enlarged partial view of the connection of the drive to the mounting head in a representation corresponding to that in FIG. 5 .
  • the wheel suspension according to the invention is an assembly made up of the parts shown in FIG. 1 .
  • FIG. 1 comprises a plate-shaped mounting head 1 , which can be assigned a corresponding fixing flange on the vehicle body (not shown specifically) in a manner not shown specifically, against which fixing flange the plate-shaped mounting head can be bolted (in a manner not shown specifically) or fixed in some other way.
  • the other parts of the wheel suspension in particular, for example, the bracket 2 , which is connected via the bearing 3 to the mounting head 1 , are attached to the mounting head 1 .
  • the bearing 3 is shown in section.
  • the bearing 3 with its center line 4 which is upright and preferably vertical to the plane of the ground, allows the bracket 2 to pivot relative to the mounting head 1 , preferably through at least 110° in both directions relative to the straight-ahead position of the wheel 5 , allowing both a transverse motion and the implementation of other steering programs that may be necessary in practice.
  • the solution according to the invention also allows rotation of the wheel through 360° relative to the axis 4 , given appropriate configuration (not shown specifically here).
  • the bracket 2 which is of L-shaped design and is connected by way of its horizontal limb 2 a to the bearing 3 , furthermore has a vertically extending limb 2 b that extends downwards from limb 2 a and to which are attached the wheel location members, which are formed by two links 6 and 7 .
  • links 6 and 7 which are pivoted to link 2 b by bearings 8 and 9 respectively and extend essentially parallel to the longitudinal center plane of the wheel 5 but to the side of the latter, link 6 forms an upper link, which extends downwards from bearing 8 at a relatively shallow angle, while link 7 forms a lower link and extends virtually horizontally.
  • links 6 and 7 extend in the direction of limb 2 a .
  • links 6 and 7 are connected by way of bearings 10 and 11 to the carrier 12 of the wheel hub motor 13 (not shown specifically), which is partially surrounded by the wheel 5 .
  • the wheel suspension and/or shock absorber strut 14 which is indicated schematically and the upper attachment point of which is assigned to that end of limb 2 a which is remote from limb 2 b , is supported at the free end of link 7 , the end adjacent to the wheel, on the other side of bearing 11 from bearing 9 .
  • links 6 and 7 preferably lie between the wheel 5 and the bracket 2 , as FIG. 2 shows.
  • the position of the wheel 5 is offset laterally relative to limb 2 b of the bracket 2 , the offset of the wheel 5 relative to limb 2 b corresponding approximately to twice the lateral offset of the bearing axis 4 relative to limbs 2 a and 2 b .
  • Limb 2 a is provided with a lateral projection, more specifically in the direction of the lateral offset of the wheel 5 , and bearing 3 is supported on this projection.
  • support is by way of a bearing plate 15 which is connected to the inner race 3 a of bearing 3 , which has an outer race 3 b that, for its part, is screwed to the plate-shaped mounting head 1 .
  • the plate-shaped mounting head 1 Concentrically to bearing 3 , the plate-shaped mounting head 1 furthermore carries a supporting ring 16 , which has a larger radius relative to the axis 4 and, as FIG. 3 shows, is not complete in view of the incomplete rotatability of the wheel envisaged here and the open ends of which end in the region of the outer edge of the wheel 5 . In relation to the straight-ahead position of the wheel, the ends are assigned stops 17 which limit the pivoting travel of the bracket.
  • the supporting ring 16 in the illustrated embodiment is designed as an internally toothed ring and interacts with a pinion 18 of a drive motor 19 that forms an actuating means and is mounted on the bracket close to limb 2 a with the axis 20 of rotation upright.
  • a pinion 18 of a drive motor 19 that forms an actuating means and is mounted on the bracket close to limb 2 a with the axis 20 of rotation upright.
  • FIGS. 3 and 4 in the illustrated embodiment it is attached by supporting struts 21 , 22 , which extend in the longitudinal direction of limb 2 a and are preferably connected in an elastically hinged manner both to the motor 19 and to the bracket 2 .
  • FIG. 3 and 4 In the plan view of FIG.
  • FIG. 5 shows, it proves expedient to use the inner race of bearing 3 as a sensor measuring ring and, for this purpose, to provide measuring marks on its face on the side facing away from the wheel 5 . If required, it is also possible to provide a corresponding marking layer.
  • the sensor or sensors 27 can expediently be assigned corresponding holders on the plate-shaped mounting head, with the result that given appropriate alignment of the mounting head relative to the vehicle body, no further adjustment work is required during assembly and disassembly.
  • the fixing plate belongs to the mounting head 1 and this fixing plate is taken out together with the other parts attached to it as an overall assembly.
  • a simplified solution is to leave the fixing plate on the vehicle and merely release bearings 3 for disassembly since the bracket and the parts attached to it, in particular, for instance, the drive and the motor 19 , can be removed with bearing 3 as an assembly.
  • the assembly is provided in the area surrounded by bearing 3 with a central aperture, formed by the interior of bearing 3 , through which all the connections to the wheel can be passed, including, for example, all the electrical and/or hydraulic connections which are not illustrated specifically here.
  • the rotary drive for the wheel set is assigned as it were to the wheel suspension as an assembly results in an increase in space and overall height within the body. Furthermore, arranging the supporting ring 16 in the manner shown allows for very large supporting-ring diameters and hence very large transmission ratios at the customary pinion size, with the result that the associated drive motor for driving the wheel set in rotation can be of relatively low-power configuration and thus operated even with conventional transmission gears.
